Which of the following is the predominant form of fats found in the human diet?
Phospholipids
Glycerols
Triglycerides
Free fatty acids
Which of the following is not true of sterols?
They contain fatty acids.
They are hydrophobic and lipophilic.
They are found in both plants and animals.
Cholesterol is an example of a sterol.
When consumed in adequate amounts, plant stanols and sterols have been shown to:
lower HDL levels in the blood.
raise HDL levels in the blood.
lower LDL levels in the blood.
raise LDL levels in the blood.
Soy, rice, and dairy-alternative products are excellent substitutes for low-fat or full-fat dairy products because dairy-alternative products:
are essentially fat free.
contain more potassium than dairy products.
contain mainly unsaturated fats.
are high in cholesterol.
Which of the following is a difference between long-chain triglycerides (LCTs) and medium-chain triglycerides (MCTs)?
MCTs consist of a glycerol backbone and only two fatty acids.
MCTs are dietary fats widely found in foods.
MCTs can be absorbed across the mucosal membrane more quickly.
MCTs are oxidized slowly.
Which of the following is a correct pairing of a fat substitute and its macronutrient(s) derivative?
Oatrim—carbohydrate and protein
Simplesse—carbohydrate
Olean—carbohydrate and fat
Benefat—protein
Which molecule makes up the backbone of all triglycerides?
Eicosanoid
Glycerol
Phospholipid
Fatty acid
Which of the following is a good example of a fat?
A piece of chicken
A banana
A pat of margarine
Some green beans
Which of the following lists the correct sequence of metabolic pathways to aerobically break down fats for energy?
Glycolysis, citric acid cycle, electron transport chain
Beta oxidation, glycolysis, citric acid cycle, electron transport chain
Beta oxidation, citric acid cycle, electron transport chain
Deamination, citric acid cycle, beta oxidation, electron transport chain
Medium-chain triglycerides (MCTs) may enhance endurance performance because they:
do not cause gastrointestinal distress
are oxidized at a lower rate than long-chain triglycerides (LCTs)
can be absorbed rapidly
increase the utilization of protein for energy
A long-term high-fat diet can:
increase an athlete’s time to exhaustion.
decrease glycogen stores.
increase the athlete’s reliance on the anaerobic system for energy production.
increase the risk for anemia.
How can fats affect daily training and competitive performance? Fat oxidation decreases as exercise intensity increases because the:
phosphagen system has an unlimited capacity to produce ATP.
aerobic system can only use carbohydrate for energy.
anaerobic system is a very complex, multiprocess pathway.
aerobic system has a slow rate of ATP production.
Which of the following is an artificial fat?
Phospholipids
Splenda
Salatrim
Acesulfame-K
Solid fats generally have a high proportion of which type of fatty acids?
Unsaturated
Saturated
Polyunsaturated
Monounsaturated
Which of the following foods naturally contains cholesterol?
Corn oil
Cashew nuts
Unsalted butter
All of these are correct.
Linoleic acid and linolenic acid are essential fatty acids.
True
False
Substances that are fat soluble are termed lipophilic.
True
False
Trans fatty acids are not common in nature but are formed during the process of hydrogenation.
True
False
Cholesterol is considered to be an essential nutrient.
True
False
Fat substitutes made from proteins can be used in baking as well as in products such as gravies, salad dressings, and frozen desserts.
True
False
Phospholipids are found in both plants and animals and have a unique molecular structure that allows them to be both fat and water soluble.
True
False
When the carbons in a fatty acid chain are all linked by single bonds, the fatty acid is termed unsaturated.
True
False
Omega fatty acid classification signifies the location of the first double bond from the carboxyl acid end of a fatty acid chain.
True
False
Linolenic acid is a common omega-3 fatty acid found in seafood, nuts, seeds, and green leafy vegetables.
True
False
Linoleic acid is the most common omega-6 fatty acid; it is found mainly in safflower, corn, and sunflower oils.
True
False
